Warrington and England prop Garreth Carvell will join the Bradford Bulls at the end of his contract in November.
The 32-year-old, who previously represented the Leeds Rhinos and Hull FC, has agreed a two-year deal to become the Bulls' first major signing for the 2014 Super League season.
Carvell has helped the Wolves win three Challenge Cups in his five seasons with the club and he is a part of Steve McNamara's England elite training squad, albeit missing out on selection for the win over the Exiles.
The signing comes a matter of days after the Bulls sold unsettled second-row Elliott Whitehead to the Catalan Dragons.
"In general we've got a young squad and most of it is about providing belief," said Bradford coach Francis Cummins.
"We just need to take the next step and the experience that Garreth brings will be invaluable in this area.
"It's a different challenge that he's going to face here but obviously the desire must still be there because he is continually striving to improve his game.
"I have spoken to him about what we need and he's delighted to be coming on board."
Chairman Omar Khan added: "We are delighted to announce Garreth as our first new signing for next season. He will be a big addition to our pack and will be a big player for us.
"Francis has outlined the club's philosophy to him and what our culture is and he has bought into that. I am sure he will be a big success at the Bulls."
